Abstract: A film including a thermoplastic resin characterized in that the film has a shear rigidity as determined in accordance with the KES method of 0.1 4.0 gf/(cm·deg) and that at least one surface of the film has a coefficient of friction as determined in accordance with the KES method of 0.15 0.80. Provided is a film which has mechanical properties necessary for use as films and is excellent in touch feeling and shear deformability which is one of the texture properties of fabric.

which accounts for 100 mass%, thermoplastic resin A being at least one resin selected from
the group consisting of ethylene-methyl methacrylate copolymer, ethylene-methyl acrylate
copolymer, ethylene-ethyl acrylate copolymer, ethylene-vinyl acetate copolymer,
ethylene-methacrylic acid copolymer, polyurethane, and polyester based elastomer.
[Claim 9]
A film as set forth in any one of claims 1 to 8, wherein layer A has a porosity of 20% or more
and 90% or less.
[Claim 10]
A film as set forth in any one of claims 1 to 9 in the form of a laminated film comprising layer
A and another film layer containing a thermoplastic resin, hereinafter referred to as layer B,
wherein layer A contains a filler, hereinafter referred to as filler A, having an aspect ratio of 1
or more and 30 or less and layer A is the outermost layer.
[Claim 11]
A film as set forth in claim 10, wherein layer B contains a filler, hereinafter referred to as filler
B, having an aspect ratio that is in the range of 10 or more and 100 or less and larger than
the aspect ratio of filler A.
[Claim 12]
A film as set forth in either claim 10 or 11 having a MB/MA ratio of 0.01 or more and 0.60 or
less wherein MA is the filler content in layer A and MB is the filler content in layer B.
[Claim 13]
A film as set forth in any one of claims 10 to 12, wherein NA - NB ^ 20% wherein NA is the
porosity of layer A and NB is the porosity of layer B.
[Claim 14]
A film as set forth in any one of claims 10 to 13, wherein thermoplastic resin B accounts for
5 mass% or more and 40 mass% or less of the total resin quantity, which accounts for 100
mass%, in layer B, thermoplastic resin B being at least one resin selected from the group
consisting of polylactic acid, polyhydroxybutyrate, polycaprolactone, polyethylene succinate,
polybutylene succinate, polyethylene adipate, polybutylene succinate adipate, polyethylene
glycol, polypropylene glycol, polytetramethylene glycol, and polyethylene
glycol-polypropylene glycol copolymer.
[Claim 15]
A film as set forth in any one of claims 10 to 14, wherein layer A, layer B, and layer A are
directly stacked in this order.
[Claim 16] ■
A laminate comprising a film as set forth in any one of claims 1 to 15 and a nonwoven fabric.
[Claim 17]
A method for producing a film as set forth in any one of claims 1 to 15 comprising a
production process having a step for foaming a composition designed for film production to
provide a film containing pores.
[Claim 18]
A method for producing a film as set forth in any one of claims 1 to 15 comprising a step for
rubbing the film.
